Pinch to zoom is nice, but relies on a sort of peripheral that most desktop computers don't have. To make a mainstream desktop system, you can't assume the user has more than a keyboard and mouse. And so the usual ctrl + / ctrl - shortcuts for scaling/zooming remain, even though they're usually superfluous to laptop users with touchpads. All kinds of things like that have been added to desktop environments. Things like hot corners to "Exposé" the windows or show all your virtual desktops, gestures for minimizing all your windows or flipping through them. Dragging windows such that they snap into certain geometries for an assisted manual sort of tiling. Despite all these additions, things which Windows 95 didn't have, the typical desktop environment would still seem reasonably familiar to a time-traveling Windows 95 user because the primary input devices are still keyboard and mouse and therefore desktop environments all work the same way, broadly speaking.
